High Durium Milpreves

Taken all the way down to base materials, one High Durium Milpreves is 3 crafting steps deep and needs 5 intermediates — Ametrine ×2, High Durium Nugget ×2, Dwarven Mythril Nugget ×1 and 2 others — which resolve to 7 distinct raw materials totalling 34 units, plus 77 crystals.

That bill outweighs 11,052 of the 13,602 recipes tracked here and 1,771 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 62 are burned by the intermediates, so the real crystal cost is 54 Wind Crystal and 23 Fire Crystal.

The chain crosses two disciplines — Goldsmith to Lv 81 and Blacksmith to Lv 81 — so no single class can finish it unaided.

All 7 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Dwarven Mythril Nugget has the widest use: 154 recipes call for it, spanning seven of the eight crafting classes.
